3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 590 km/s at 15/0558Z. Total IMF reached 5 nT at 14/2100Z. The maximum southward component of Bz reached -4 nT at 14/2317Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2846 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to major storm levels on day one (16 Oct), unsettled to minor storm levels on day two (17 Oct) and quiet to unsettled levels on day three (18 Oct). Protons have a slight chance of crossing threshold on days one, two, and three (16 Oct, 17 Oct, 18 Oct).
Solar ActivityAnalysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 5 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (16 Oct, 17 Oct, 18 Oct).
